Photovoltaics | Department of Energy

Photovoltaics. Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels.

Solar Cells: How They Work and Their Applications

Solar cells are the building blocks of solar panels, which are commonly used for power generation in residential, commercial, and utility-scale applications. The term "photovoltaic" is derived from the Greek word "phos," meaning "light," and "voltaic," in reference to the Italian scientist Alessandro Volta, who is credited with

Solar panel

Solar array mounted on a rooftop A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in
